Aquatic Ecosystems Practice Flashcard

Front

What factors influence salinity levels in aquatic ecosystems?

Back

Salinity levels are influenced by rainfall and evaporation.

Front

What is the continental shelf in the context of coastal oceans?

Back

The continental shelf is a shallow border that surrounds the continents.

Front

What is the 'twilight zone' in the ocean?

Back

The 'twilight zone' is known as the Dysphotic zone.

Front

How does acid rain affect aquatic ecosystems?

Back

Acid rain lowers pH and harms aquatic ecosystems.

Front

What role do marine ecosystems play in the environment?

Back

Marine ecosystems regulate climate.

Front

Define salinity in aquatic ecosystems.

Back

Salinity is the concentration of salts in water, affecting aquatic life.

Front

What is the euphotic zone?

Back

The euphotic zone is the upper layer of water where sunlight penetrates, allowing photosynthesis.

Front

Explain the aphotic zone.

Back

The aphotic zone is the deep ocean layer where no sunlight reaches, inhibiting photosynthesis.

Front

What is the significance of the dysphotic zone?

Back

The dysphotic zone is where light is insufficient for photosynthesis but some light is present.

Front

How does temperature affect aquatic ecosystems?

Back

Temperature influences metabolic rates and species distribution in aquatic ecosystems.
